I changed the unlock code on my phone and now i cant remember it.

you will need to hook it up to the original computer that was used during setup and restore the phone to factory setting if you cant remember your pass code

try 0000
or 123456

try *2767*3855# or press and hold home button +power on button and reset factory settings. it will unlock.

yes, the first basic solution to unlock a code is to RESTORE FACTORY SETTINGS of your cp.

hello:

IMEI: 357082/00/165797/9

Master Code: 1760007606

this is your 10 digit master code.. keep is safe because this cant be changed, only security code can be changed.
this code will work everywhr whr it asks for SECURITY CODE (ex keypad unlock with security code, reset phone to factory settings, etc.)
